This data set was collected on RRS Charles Darwin cruise 62 (CONVEX 91) as a contribution to WOCE core Project 3. The data set comprises high quality CTD, nutrient, dissolved oxygen, and CFC data between the UK and Cape Farewell, Greenland. These data were collected to investigate the distribution of water masses and to derive full depth circulation. Two approximately meridional sections were completed with linking sections on 20 W and 30 W. Two drifting buoys were deployed during the cruise.
